So, you want to know about everything that's new in Android 4.3. Every single change that's occurred since 4.2.2. Well, if you don't mind scrolling through a barely-human-readable, mile-long developer changelog, now you can satisfy that urge.

Al Sutton has posted a wonderfully-formatted AOSP commit changelog covering the changes from Android 4.2.2 (JDQ39) to Android 4.3_r2.1 (JSS15J). The JSS15J build is the most recent release of 4.3, and is the one currently shipping on the new Nexus 7. Older Nexus devices are currently on slightly older builds (prefixed by "JW") in order to protect them from destabilizations that might have been caused by last-minute changes to AOSP specifically for new N7.

We've published these changelogs as embedded elements in the past, but Al's done such a great job formatting and cleaning up things that there's really not a point, so be sure to head to his page to check it out. Who knows what could be lurking in there!

You can check out our previous developer changelogs, too - Android 4.2.2 is here, and Android 4.1.2 is here. Finally, if developer changelogs aren't exactly your thing, check out these posts discussing in a more general sense 'what's new in Android 4.3?':

ya ya...feeling happy with 4.3...fuck! ...google, what's wrong with you? the gesture keyboard was already very nice and convenience to use after 4.2.2 update. Now the same problem coming back again... just highlight ONE of the problem, during key-in web page, swipe 2 words like androidpolice.com, it will not have space between android and police. Now in 4.3, it happen again, new version with old problem which already been fixed.

It's fixed if you download Google Keyboard from the Play Store. It's not fixed in the AOSP keyboard.

I like that there is one less step involved when adding a new word to the dictionary. :) (Touch to save and that's it)

Isn't that the keyboard's commands, not the OS's?

it still does it on 4.2 with the new keyboard update vs 4.3 for me. im just happy no matter where the change resides that it is gone

Oh. I use the stock keyboard on my HTC One (still on 4.1.2 :( ), but I don't get the annoying pop-up when adding to dictionary anymore.
